As requested, here's one of the scenes I've been testing. If you look
closely, you'll see some reflective caustics coming out of the sphere
and cylinder. The chrome ball also reflects light, but it gets dispersed
so much that it's very difficult to see.
size: 320x240
aa: 0.3
render time: 2:28
number of photons: 61,805
peak memory used: 5,821,710

sigh - beautiful !
Once your patch will come out, I think the IRTC could
do a new "glass" round...

Hi !
That looks great !
One thing : What are the numbre of photons you mentionned. Is it a new feature
which is going to be implemented ?

Yes, the photons are part of a new feature in my custom compile of POV
(should be available in a few weeks).

Wow... and wow, look at the memory used. I would have expected a measely
50K not 5M! Those photons aren't your everyday variety of quanta
particles, are they?
Render time looks good though. Seeing caustics as they ought to be is a
ray of sunshine in a (media) cloudy world.

Yes, I have not yet optimized this to minimize memory usage (I've been
focusing mostly on speed). Each photon currently has two vectors (for
position and direction), and each of those vectors has three floats.
Then add color, some pointers for the kd-tree struct, and you've got
a fairly large memory structure. I'm hoping to re-code some of the
kd-tree so I don't need pointers, and cram the direction vector into
two characters (phi & theta angles... but that might slow things down
because I'll have to decode those into another vector using sin & cos).

By changing some parameters (using the same number of photons), I got
the render time down to 1:47 with only a very slight decrease in
image quality, FYI. (After jpg compression, you can't tell the
difference, so I won't repost.)
